DLP, or Digital Light Processing, is a technology that employs a digital light processing chip covered with thousands to millions of tiny mirrors to reflect light and create images. This type of projector utilizes a Digital Micromirror Device (DMD) chip, which is crucial for its operation. When light is directed onto this chip, the individual mirrors tilt to reflect the light either toward the screen or away from it, thus forming the image.

DLP projectors are known for their sharpness, brightness, and the ability to display rich colors, primarily due to the rapid switching of light and the effective manipulation of color through a color wheel or LEDs. This technology contributes to the overall performance and quality of the projected images, making DLP projectors a popular choice for various applications.

In contrast, LCD projectors use liquid crystal displays to create images, which function quite differently from a DLP chip. LED projectors typically rely on LED light sources and may use either DLP or LCD technology to form images. Laser projectors utilize lasers as a light source, and while they can work with DLP technology, they do not inherently use a DLP chip as their defining characteristic.
